I want to open website URL to download PDF file from windows service for every 2 minutes, I am using following criteria but it's not opening the URL and not giving any error

What I have tried:

I tried Below

<pre> ProcessStartInfo sInfo = new ProcessStartInfo("www.google.com");
       Process.Start(sInfo);

Thread.Sleep(100000);

After opening this URL I am closing this process as follows

Process[] AllProcesses = Process.GetProcesses();
foreach (var process in AllProcesses)
{
    if (process.MainWindowTitle != "")
    {
        string s = process.ProcessName.ToLower();
        if (s == "iexplore" || s == "iexplorer" || s == "chrome" || s == "firefox")
            process.Kill();
        writelog("Browsser closed Files");
    }
}

The above same code is working in windows form application but in windows service it's not working, Please assist to solve this
